Arsenal boss Wenger: I will try to make signings as quickly as possible
William Gallas, Sol Campbell and Mikael Silvestre will all see their deals finish at the end of the season, so Wenger may well look to bolster his defence, with Fulham centre-back Brede Hangeland a potential target.
"I will try to do what I want to do as quickly as possible, but it does not only depend on me," he said.
"Certainly, we will announce one player before the World Cup, but after that we will see."
Wenger, however, maintains his playing staff does not need major surgery, saying: "I believe in the squad I have and if I can make an addition to the squad - two or three maximum - then we will do it."
